Der Erfindung liegt daher die Aufgabe zugrunde, eine mit Dampf beheizbare Hohl-Walze der gattungsgemäßen Art so auszugestalten, dass eine exakte Einstellung des Abstandes zwischen Absaug-Öffnung und Innen-Wand der Hohl-Walze auch während des Betriebes der Hohl-Walze möglich ist.The invention is therefore based on the object, a heatable with steam hollow roller of the generic type so that an exact adjustment of the distance between the suction opening and inner wall of the hollow roller is also possible during operation of the hollow roller.
Diese Aufgabe wird gemäß der Erfindung durch die im Kennzeichnungsteil des Anspruches 1 angegebenen Merkmale gelöst. Da die Einstellung des Abstandes zwischen der Innen-Wand der Hohl-Walze und der Absaug-Öffnung des Siphon-Rohres durch eine Verschwenkung der außerhalb der Hohl-Walze liegenden, und sich nicht mit dieser drehenden Dreh-Durchführung vorgenommen wird, ist eine solche Verstellung auch während des oft hochtourigen Betriebs einer solchen Hohl-Walze ohne Weiteres möglich. Auch Nachjustierungen während des Betriebes sind möglich, ohne dass eine Fertigungs-Anlage, in der sich die beheizbare Hohl-Walze befindet, angehalten werden muss. Ein Anliegen des Siphon-Rohres an der Hohl-Walze und damit eine Einschleifen kann damit vermieden werden. Das Einstellung des Abstandes der Absaug-Öffnung von der Innen-Wand kann während des Betriebes in der Weise erfolgen, dass das Siphon-Rohr mit seiner Absaug-Öffnung gegen die Innen-Wand der Hohl-Walze angelegt wird. Dies kann akustisch oder durch Schwingungs-Messung erfasst werden. Anschließend wird die Dreh-Durchführung um einen vorgegebenen Winkel verstellt, womit exakt die Höhe des Spaltes zwischen Absaug-Öffnung und Innen-Wand festgelegt wird. Hierzu kann an der Dreh-Durchführung eine entsprechende Anzeige angebracht werden.This object is achieved according to the invention by the features stated in the characterizing part of
